POWER TRAIN:AUTOMATIC TRANSMISSION
AUTOMATIC TRANSMISSION DOES A "CLUNK" SOUND (AS IF IT WAS SHIFTING TO A GEAR) IN "DRIVE" WHILE AT A COMPLETE STOP. WHEN STOPPING AT A STOP SIGN OR A STOP LIGHT, APPROXIMATELY 15 SECONDS AFTER THE COMPLETE STOP, THE TRANSMISSION "CLUNKS" INTO WHAT SOUNDS AS IF IT IS SHIFTING INTO A GEAR (PROBABLY FIRST GEAR). THIS HAD BEGUN INFREQUENTLY, BUT IS NOW OCCURRING MORE OFTEN, AT LEAST ONCE A WEEK NOW. I HAD THE DEALER LOOK AT IT WHILE STILL UNDER WARRANTY, BUT THEY STATED NO "CODES" WERE SHOWING UP ON THE COMPUTER. WHAT THEY ENDED UP DOING IS GREASING THE ENDS OF THE DRIVE SHAFT, STATING THAT WAS THE PROBLEM. HOWEVER, THIS ISSUE CONTINUES. IT COULD BE A COMPUTER PROGRAM PROBLEM. *TR
